Fixes test error about missing annotation_reader

Starting in Composer 2.1 & Symfony 5.3, whether the annotations system is auto-enabled
depends on whether doctrine/annotations will be available *without* taking into account
dev dependencies. In MakerBundle, when we boot a test container, doctrine/annotations
is a dev dependency only (appropriately), which incorrectly hints to the container
that the system should not be initialized. So, we force it.
